right before that last line, I get a response immediately. Alle the debug information I have put before that...

When I put it after that, it takes forever (I always stopped after two or three minutes at latest).

Now however, I have to say, that it works again. No idea way. And I will only start to care, if it happens again ;-)

P.S. The getting stuck was no isolated incident. I have tried a dozen times over the course of two days. Maybe there were some issues with my provider? That the curl call simply didn't go out from their servers? I don't know...
